I've not had a chance to boot-test this patch yet, but it is insufficient as-is with a default config due to the default being my repo/my coreboot_fb branch. One would need to change the git revision to upstream/master for this to build even.
Until UefiPayloadPkg reaches feature/functional parity with my existing fork, what might make sense is to add a Kconfig option to select CorebootPayloadPkg (using my repo/branch) or UefiPayloadPkg (using upstream/master) and leave the default as-is
I tested a separately build UefiPayloadPkg (qemu). Specifying the PCIE_BASE was needed and PS2 keyboard did not work. Other than that, it does boot.
Okay, PCIE_BASE is needed. Did you get a chance to try on real platform, last time I tried and that can't boot up as well. May I know what you have done to add PCIE_BASE? Thanks.
